DAS-EDU Visual Fiber Optic Sensing Teaching Instrument

1.Product Development Background

As a professional fiber optic hardware manufacturer, YBPhotonics provides a full range of modular components for building Φ-OTDR and DAS systems. However, the modular assembly method requires high professional proficiency, precise wiring and careful operation—incorrect operation may easily cause fiber breakage or optical component short circuits, which is not suitable for teaching scenarios with large student operation volume. To solve this teaching pain point, we independently developed the DAS-EDU integrated teaching instrument, which optimizes the operation difficulty and improves the safety and teachability of fiber optic sensing experiments.

2.Our Solution

The DAS-EDU educational instrument integrates all core fiber optic sensing modules into a 400×290×73mm aluminum alloy enclosure, realizing a compact and integrated design for teaching scenarios. Its high-transparency acrylic front panel clearly displays all internal system components, and the system wiring schematic is printed directly on the panel for intuitive principle understanding. All module connectors are centrally arranged on the side panel for easy hands-on operation, allowing students to complete physical connection independently and deepen their understanding of fiber optic sensing system structure.
